Telstra is soon to be offering a service called iCall which makes it possible to receive calls on a phone line while it is in use by a modem. Unfortunately it require Microsoft Netmeeting to operate, which means its only available to Microsoft Windows users. I would really like to use this service, but I usually dialup using linux as that way other computers on my home network can make use of the dialup connection. I wonder if anybody implemented the netmeeting functionality under linux?

Update

According to Linux Netmeeting HOWTO Netmeeting uses the H.323 protocol for video conferencing, the T.120 protocol for application and file sharing, and LDAP for the directory service. There is an opensource implementation of H.323 called OpenH323. OpenH323 development is coordinated by an Australian company.
